Abstract

A novel rec-L-N-carbamoylase from Arthrobacter aurescens and its method of use for producing L-amino acids. The recombinantly produced L-carbamoylase is unexpectedly stable, so that an industrial method of producing L-amino acids can be established with it, in contrast to previously known L-carbamoylases.
